Cellular concrete is a mixture of cement, water, and preformed foam. The purpose of the foam is to supply a mechanism by which a relatively high proportion of stable air voids can be induced into the mixture and produce a cellular or porous solid upon curing of the mixture.
What is the use of cellular concrete?
The cellular lightweight concrete is used as thermal insulation in the form of bricks and blocks over flat roofs or non-loading walls. Bulk filling by applying relatively low strength material for old sewer pipes, wells, unused cellars and basements, storage tanks, tunnels, and subways.
What is the difference between cellular concrete and regular concrete?
Regular concrete uses small stone as one of its main ingredients. Cellular concrete replaces this small stone with tiny air bubbles, which are created by the blending of foam ingredients as the concrete is mixed.
How strong is cellular concrete?
The standard cellular concrete mix weighs 30 pcf, with an average compressive strength of approximately 100 psi (14,400 psf).
What is the meaning of cellular concrete Related Questions
What is concrete best definition?
concrete, in construction, structural material consisting of a hard, chemically inert particulate substance, known as aggregate (usually sand and gravel), that is bonded together by cement and water. concrete.
What is the definition cellular construction?
box frame construction, also called cellular framing, or cross-wall construction, method of building with concrete in which individual cells, or rooms, are set horizontally and vertically together to create an overall structural frame.
What are the benefits of concrete?
Durability. Most concrete buildings are designed to last at least 30 years in service, although many last longer before deteriorating to the point of repair or replacement. Fire Resistance. Cost. Construction Speed. Energy Efficiency. Versatility. Low Maintenance.
What are the disadvantages of cellular concrete?
The main disadvantage of cellular concrete, on the other hand, is its brittleness ‚Äì the block may break if dropped on a hard surface. Another disadvantage of aerated concrete is the need for additional insulation in walls made of cellular blocks.
What are the properties of cellular concrete?
Cellular concrete consists of cement, water, aggregate and air voids. Cellular concrete can have between 10% and 70% air, which results in a material that is lightweight but may compromise the compressive strength and durability properties.
What are the advantages of cell filled concrete?
The cost of construction is much reduced when contrast to standard cement concrete pavement. Use of recycled plastic. If the personal block fails, it can easily return without much effort and with the least cost.
Which concrete is best for building?
#1 – Portland Pozzolana Cement. #2 – Ordinary Portland Cement, 43-Grade Cement. #3 – Ordinary Portland Cement, 53-Grade Cement. #4 – Portland Slag Cement. #5 – Hydrophobic Portland Cement. #6 – Rapid Hardening Cement. #7 – Sulfate Resisting Portland Cement.
Which concrete is best for slab?
The Best Type Of Cement For Concrete Slabs Different types of cement are used to construct concrete slabs, but the best would be Portland Pozzolana Cement (PPC). People use PPC to produce concrete for homes, residential areas, and schools. PPC is made of cement clinker (77%), gypsum (3-5%), and fly-ash (20%).
How long does it take for cellular concrete to cure?
Placed in moderate temperatures, LCC will set and harden within approximately 10 to 14 hours.
What is the strongest type of concrete?
Ultra-High Performance Concrete (UHPC) is a cementitious, concrete material that has a minimum specified compressive strength of 17,000 pounds per square inch (120 MPa) with specified durability, tensile ductility and toughness requirements; fibers are generally included in the mixture to achieve specified requirements …
What is the strongest cement concrete?
Portland cement concrete (PCC) ‚Äì this type of concrete is made of sand, crushed stone, andPortland cement. It has a high density, which makes it strong but also increases its cost.
What are the 3 types of concrete?
There are three different types of concrete: Portland cement, aggregate, and water. Portland cement is the main ingredient in concrete.
What is a concrete explanation example?
Concrete examples are specific, real-life examples used to illustrate an idea. They can be useful in helping participants grasp abstract concepts because they present the conceptual elements in a recognizable context. Concrete examples can be verbal descriptions, stories, actual objects (realia), and models.
What are examples of concrete meaning?
Concrete words refer to tangible, qualities or characteristics, things we know through our senses. Words and phrases like “102 degrees,” “obese Siamese cat,” and “deep spruce green” are concrete. ABSTRACT: To excel in college, you’ll have to work hard.
What was the meaning of cellular?
cel¬∑‚Äãlu¬∑‚Äãlar Ààsel-y…ô-l…ôr. : of, relating to, or consisting of cells. a cellular structure. cellular growth. : cell-mediated.
Why is it called cellular?
It all started when two engineers Douglas H. Ring and W. Rae Young from Bell Labs set out to build a cellular telephone network around 1947. While developing the layout of a network or wireless towers, they chose the term ‘cellular’ as the coverage map looked like a group of biological cells.
